| VAR-202101-1926 | CVE-2021-3156 | Sudo set_cmd() is vulnerable to heap-based buffer overflow |
CVSS V2: 7.2 CVSS V3: 7.8 Severity: HIGH |
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. A heap-based overflow has been discovered in the set_cmd() function in sudo, which may allow a local attacker to execute commands with elevated administrator privileges.CVE-2021-3156 AffectedCVE-2021-3156 Affected. These packages include redhat-release-virtualization-host,
ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user
interface for monitoring the host's resources and performing administrative
tasks.
Bug Fix(es):
* Previously, the Red Hat Virtualization Host (RHV-H) repository
(rhvh-4-for-rhel-8-x86_64-rpms) did not include the libsmbclient package,
which is a dependency for the sssd-ad package. Consequently, the sssd-ad
package failed to install.
With this update, the libsmbclient is now in the RHV-H repository, and
sssd-ad now installs on RHV-H. (BZ#1868967)
4. Bugs fixed (https://bugzilla.redhat.com/):
1850939 - Hosted engine deployment does not properly show iSCSI LUN errors
1868967 - sssd-ad installation fails on RHV-H 4.4 due to missing libsmbclient from samba package in rhvh-4-for-rhel-8-x86_64-rpms channel
1889686 - CVE-2020-25684 dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker
1889688 - CVE-2020-25685 dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker
1890125 - CVE-2020-25686 dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker
1902315 - Rebase RHV-H 4.4 to RHV 4.4.4
1902646 - ssh connection fails due to overly permissive openssh.config file permissions
1909644 - HE deploy failed with "Failed to download metadata for repo 'rhel-8-for-x86_64-baseos-beta-rpms': Cannot download repomd.xml
1917684 - CVE-2021-3156 sudo: Heap buffer overflow in argument parsing
1921553 - RHVH upgrade to the latest 4.4.4-1 build will fail due to FileNotFoundError
1923126 - Hosted Engine setup fails on storage selection - Retrieval of iSCSI targets failed. # Exploit Title: Local Privilege Escalation - LPE
